Google AI (Gemini)

To enable Google AI models with Letta, set GEMINI_API_KEY in your environment variables.

You can use Letta with Google AI if you have a Google API account and API key. Once you have set your GEMINI_API_KEY in your environment variables, you can select what model and configure the context window size.

Enabling Google AI with Docker

To enable Google Gemini models when running the Letta server with Docker, set your GEMINI_API_KEY as an environment variable:

$ # replace `~/.letta/.persist/pgdata` with wherever you want to store your agent data
> docker run \
>   -v ~/.letta/.persist/pgdata:/var/lib/postgresql/data \
>   -p 8283:8283 \
>   -e GEMINI_API_KEY="your_gemini_api_key" \
>   letta/letta:latest

See the self-hosting guide for more information on running Letta with Docker.
